Disclaimer

This calculator provides estimates based on mathematical formulas. The US Navy Method and BMI-based method are screening tools, not diagnostic measures. Accuracy varies based on individual body composition.

This is not medical advice. Body fat distribution, muscle mass, bone density, and other factors affect health outcomes beyond what these formulas can measure. For precise body fat measurement, consider methods such as DEXA scans, hydrostatic weighing, or professional calipers.

Always consult a healthcare professional before making significant changes to your diet or exercise routine.
